Abstract:

To reveal the morphological and physiological differences between male and female individuals, we compared the morphological traits,tuber yield at maturity and inclusions contents for different genders of yam. The results showed that the female individuals had fewer branches, relatively lower leaf density, shorter tuber neck length, and higher tuber yield. The content of soluble protein and total phenolics in female tubers were higher than those in male tubers, and the content of starch, polysaccharides, saponins, and flavonoids was not significantly different between male and female individuals. Among the 17 amino acid components, the content of glutamic acid in female individuals was higher than that in male individuals, while the remaining 16 amino acids showed no significant difference between male and female individuals. The differences in the morphology and inclusions, which can be used as an indicator for the identification of male and female individuals, need further research.
